MD5Crypt alternative in swift

[trivarialthea]

Hi!
How would one implement md5crypt (hashing using md5 + specific salt, prefixing it with "$1$" and doing this 1000 times) in swift?
I can not find any library for this in swift and CryptoKit MD5 function does not have that implemented (my attempts to replicate this were unsuccessful using CryptoKit).

MD5Crypt function explanation: here

(I have to use MD5 because i try to interface with a specific api that requires passing the credentials as hashed md5 strings.)

Thanks for any help in advance!
